Recap of Hot Socket Presentations

February 4th – Presentation by Scott Weikel, ANSI C12

ANSI C12 is developing extensions to the metering standards to

cover general safety, including thermal aspects

April 2nd – Presentation by Underwriters Laboratories

UL has developed a safety test procedure for solid state electricity

meters: UL 2735 - Electric Utility Meter Safety Standard and

Conformity Assessment

Both presentations and webcast recordings are available

AMI Prognostics and Heath Management Guide

• Started in 2013, with

participation of utilities and AMI

vendors

• Continued emphasis as a high-

value activity in EPRI program

• Contributions from key

component manufacturers

• Engagement with other

industries through IEEE P1856

• 2013 Outline Report

Common Process Development Initiative

AMI Prognostics and Heath Management Guide

• Working group meeting weekly throughout 2014

– you are welcome to participate

• Engagement of Arend Koert (Kinectrics) – expert in

metering accelerated life testing

• Recent focus has been the sampling processes that are

used for each PHM process

• Continued EPRI interest in conducting a PHM Business

Case workshop with CALCE in 2015. Would you attend?

2 to 150 KHz Impact on Meters

• Previously reported-on in this forum

• Issues noted with certain IEC meter types.

• Ongoing action in IEC: 61000-4-19

– EMC testing for meters – test for immunity to conducted,

differential mode disturbances in the 2 to 150KHz range

• 2014 EPRI project – working with Hydro Quebec to test

ANSI meters in the same way. Test design and setup in

process, will report back findings

IntelliGrid – Project Set FAdvanced Metering Systems

Project Set Lead:

Brian Seal

(865) 218-8181

Four Parts:

1. Open standards and interoperability

2. Optimizing the value of AMI systems through

new uses and value streams

3. Meter/AMI O&M: identifying best practices for

selection, deployment, operation, maintenance,

management, lifecycle planning

4. The meter: investigating solid state meter

performance, accuracy, and reliability

11© 2014 Electric Power Research Institute, Inc. All rights reserved.

161F Sub-Project: 1. Open standards and interoperability

Issue

• AMI systems are proprietary and utilities

are locked-in to single sources of supply

• Lack of competition results in higher prices

and lack of innovation

• Vendors are not inclined to change

Approach

• Developing an open reference architecture

and components

• Direct contribution to standards

organizations guide the direction of industry

• Vendor engagement, interoperability

workshops

161F Sub-Project: 2. Optimizing Advanced Metering System Value and Utilization

Issue

• AMI systems have the potential to be utilized in many ways and their data to be processed for many purposes.

• Need to identify and prove-out potential additional uses of AMI systems and data. System impacts and benefits need to be quantified in order to aid utilities in business case development and in optimizing the value of AMI assets.

Approach

• Work collaboratively, sharing experiences and learnings

• Perform data analytics and laboratory evaluations

• Work with meter manufacturers directly

161F Sub-Project: 3. Advanced Metering Systems Operations and Management

Issue

• Management and operation of AMI fixed networks

is a new endeavor for many utilities.

• The systems are recent inventions, and best

practices re just being discovered for their

deployment, operation, health monitoring,

management, and replacement.

Approach

• Track industry experiences.

• Utility focus groups developing common approaches

• Engaging subject-matter experts to document best

practices. Assess together, refine.

161F Sub-Project:

4. Meter Performance and Reliability Testing

Addressing the meter-centric topics that are regularly discussed in this forum:

–Hot socket detection

–Meter over voltage tolerance/sensitivity

–DC field (currents and magnets)

–Accelerated life testing

– 2 to 150 KHz sensitivity
